SPECIFICATION forming part of Letters latent N 0. 740,233, dated September 29, 1903.

Application filed January 13,1902. Serial No. 89,600. (No model.) 7

To all whom it may concern:

Be it known that I, FRANK I. CLARK, of Augusta, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Attachments for Printing-Presses or other Machines, of which the following is a specification.

My invention relates to an attachment for printing-presses and other machines using paper in sheet or roll; and its object is to prevent the paper in process of printing from becoming electrified by the friction of the moving parts of the press or machine or to remove electricity in the process of printing from paper already electrified. To this end I locate adjacent to the revolving drum or cylinder or section most convenient to the moving paper 21, Well or fountain provided with a liquid or with any desired solution and locate in said Well or fountain a number of wicks which are adapted to be turned up or down and which becoming saturated with the liquid or the solution and coming in contact with the paper act in such manner as to remove or dissipate the electricity from the paper as it passes through the press or the machine, thus preventing the paper from' absorbing the electricity generated by the friction of the moving parts of the machine or removing electricity previously deposited in the paper. This generation of electricity occurs more particularly in winter, and especially on dry days, making it difficult to handle the paper under such conditions.

My invention consists of certain novel fea-\ tures hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying my invention, Figure 1 is a perspective view showing my improved attachment applied to the ordinary cylinder printing-press. Fig. 2 is a detail side view of my improved attachment. Fig. 3 is a similar view looking from the other side. Fig. 4 is a sectional view through the well and showing the wick in position.

Like letters of reference refer to like parts throughout the several views.

The paper on the table A passes round the drum B, revolved by the gear-wheel C, which is driven by the driving-wheel D. The grippers E for keeping the paper in motion are the knurled rod H operated by the gears F, F, F and Win the usual manner. Below the grippers E is located the guide G, which prevents the paper from falling off and guides it round the drum. Secured to said guide-frame G are two lugs G, in which are fixed the shafts G of the Well or fountain H. This well or fountain, which may be of any desired shape, has a number of upward projections H, through which wicks K are adapted to move, and said wicks are moved up or down, as desired, by

In this well or fountain is placed a liquid or any desired solution, whichis adapted to be taken up by the Wicks and conveyed to the paper, so as to remove or to dissipate any electricity that might be in the same and also to prevent the paper from becoming electrified as it passes through the machine. Suitable covers H are provided for each of the projections H, and said projections H are covered when it is desired to do so in case the paper to be printed is not as wide as the well. This attachment may be applied to any kind of a printing-press or other machine using paper, whether fed from single sheets or from a continuous roll, and secured in position in any desired manner, as the drawings simply illustrate a convenient means of. locating the attachment on the ordinary handfed cylinder-press. The lugs Gmay be provided with slots G so that the well or fountain can be raised and lowered, and the attachment can be secured in place by the setscrews J on each end.

I donot limit myself to the arrangement and construction shown, as the same may be varied without departing from the spirit of my invention.

Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is j 1. In an attachment for printing-presses, a fountain located adjacent to the path of travel of the paper through the press, a plurality of wicks placed in said fountain, and mechanism for moving said wicks relatively to the path of travel of the paper through the press.

2. In an attachment for printing-presses, a fountain located adjacent to the path of travel ICO of the paper through the press and provided with a plurality of openings, wicks placed in said fountain and adapted to be projected through said openings, covers for said openings, and mechanism for moving said wicks independently of each other through said openings to and from the path of travel of the paper through the press.

3. In an attachment for printing-presses, a fountain adjustably mounted adjacent to the path of travel of the paper through the press, a plurality of wicks placed in said fountain, and mechanism for moving said Wicks rela tively to the path of travel of the paper though the press.

4. In an attachment for printing-presses, a fountain adjustably mounted adjacent to the path of travel of the paper through the press and provided with a plurality of openings, v
